基于负载转矩滑模观测的永磁同步电机滑模控制OA北大核心CSCDCSTPCD
Sliding Mode Control of PMSM Based on a Novel Load Torque Sliding Mode Observer
为了减小负载转矩扰动对永磁同步电机（permanentmagnet synchronous motor,PMSM）控制系统的影响,提高系统抗扰能力,提出一种以转速和负载转矩为观测对象的扩展滑模观测器,以实际转速与观测转速之差构成滑模面,负载转矩观测结果由负载转矩实际值和经过滤波后的抖振信号组成,当滑模运动发生后转矩观测误差渐进收敛到零。设计了基于指数趋近律的PMSM滑模控制（sliding-modevariable structure contr…查看全部>>
An extended sliding-mode observer of the load torque was proposed,of which the state variables were speed and load torque,in order to decrease influence of varying load torque in a permanent magnet synchronous motor（PMSM） control system.Errors between the real and the observed speed were selected as a sliding-mode hyper plane,and the observed load torque was composed of a real load torque and the filtered chattering signal.The observation error converged to …查看全部>>
